Brief The beautiful marble buildings and statues in Vienna are being eroded by acid rain Investigate the rate of this reaction in the lab, using calcium carbonate and hydrochloric acid Factors that can change the rate of reaction: *Surface area of the calcium carbonate *Weight of the calcium carbonate *Concentration of the calcium carbonate (purity) *Concentration of the hydrochloric acid *Volume of the hydrochloric acid *The temperature the reaction takes place at Background knowledge This is the reaction that I will be investigating: calcium + hydrochloric = calcium + water + carbon carbonate acid chloride dioxide CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(l) Hypothesis From background knowledge I have determined that the higher the concentration the acid the faster the reaction will take place because the more acid particles there are in a solution the more likely there is a chance of getting a reaction. In this diagram you see that there is more water than acid so the acid has less chance to hit the calcium so the reaction will...
